Answer:

31/36

Step-by-step explanation:

P(E or M) = P(E) + P(M) - P(E & M)

= (2/3) + (4/9) - (1/4)

= 31/36

How to I find this? I tried using Pythagorean theorem, but it didn't work

jarptica [38.1K]

The Pythagorean theorem works.

$12^2+9^2=c^2$
$144+81=c^2$
$225=c^2$
$15=c$

Therefore the perimeter is 12 + 9 + 15 = 36 in. (B)

Solve for x in the equation 2x2-5x+1=3

Butoxors [25]

2x^2 - 5x + 1 = 3

Subtract 3 from both sides
2x^2 - 5x + 1 - 3 = 3 - 3

2x^2 - 5x - 2 = 0

Use quadratic formula with A = 2, B = - 5, C = - 2

x = - b +- sqrt b^2 - 4ac/2a

x = - ( - 5) +- sqrt (- 5)^2 - 4(2)( - 2)/(2)(2)

x = 5 +- sqrt 41/4

x = 5/4 + 1/4sqrt 41 or x = 5/4 + - 1/4 sqrt 41

Answer: x = 5/4 + 1/4 sqrt 41
x = 5/4 + - 1/4 sqrt 41

Hope that helps!!!!! (D)
